Diagnostic Information and Procedures
Battery InspectionS7RS0B1A04001
Common Causes of Failure
A battery is not designed to last indefinitely; however, with proper care, it will provide many years of service. If the
battery performs satisfactorily during te st but fails to operate properly for no apparent reason, the following are some
factors that may point to the cause of trouble:
• Accessories left on overnight or for an extended period without the generator operating.
• Slow average driving speeds for short periods.
• Electrical load exceeding generator output partic ularly with addition of aftermarket equipment.
• Defects in charging system such as high resistance, s lipping drive belt, loose generator output terminal, faulty
generator or voltage regulator, Refer to “Generator Symptom Diagnosis”.
• Battery abuse, including failure to keep battery cable terminals clean and tight or loose battery hold down.
• Mechanical problems in electrical sys tem such as shorted or pinched wires.
Visual Inspection
Check for obvious damage, such as cracked or broken case or cover, that could permit loss of electrolyte. If obvious
damage is noted, replace battery. Determine cause of damage and correct as needed.
Generator Symptom DiagnosisS7RS0B1A04002
CAUTION!
• Do not mistake polarities of “IG” terminal and “L” terminal.
• Do not create short circuit between “IG” and “L” terminals. Always connect these terminals through a lamp.
• Do not connect any load between “L” and “E” terminals.
• When connecting charger or booster battery to vehicle battery, refer to “Jump Starting in Case of Emergency”.

Trouble in charging system will show up as one or more of the following conditions:
1) Faulty indicator lamp operation.
